Film-forming materials based on metal chalcogenides (sulphides, selenides, tellurides) are mainly used as high-refracting components of multi-filmed interference coatings in the IR-, more rarely in the visible spectrum range.
Depending on the type of the evaporating installation and the chemical composition, FFM can be supplied in the form of granules, tablets and targets of the required size.Application
For manufacturing optical interference antireflection; anti-reflective; protective coatings on optical parts (prisms, lenses, filters) made of glass, monocrystals, optical ceramics, etc.:
by the method of vacuum electronic-beam and resistive evaporation;
by the method of magnetron and ion-plasma sputtering.
Today our company is the only Russian manufacturer and developer of high-purity materials for thin-filmed optics. We can produce the FFM with the form and size by a customer’s request. Besides we can develop and produce the required FFM composition according to your technical specification.
